Remote control cars are usually used for recreational purposes. People use them as toys and equipment related to their hobbies. However, an RC car not working can be very frustrating for individuals, especially if they suddenly give up or refuse to start.
These problems may seem so difficult to resolve that people might find it easier to invest in another RC car. However, most often these problems are easy to fix and require a fundamental knowledge of the system and functioning.
Having a brief idea about the working of the RC car enables people to diagnose the problems on their own, fix RC car and know when to hand over the situation to an expert in case of complicated adjustments and repairs.
The following tips explain how to fix remote control car:
Switching the Device On
When the RC car refuses to start, the user immediately starts thinking that something must be wrong with the machine. However, as silly as it may sound, most people forget to switch on the transmitter of the device.
Therefore, one must make sure that the transmitter is switched on for the car to start and work properly. Moreover, if the car refuses to work despite the switch being on, the user must switch the transmitter off before inspecting any further.
Battery-related problems can cause the car to function slowly, stop working suddenly or make it impossible to start, in the first place. Before you think that your RC car is broke, check the batteries and their alignment. First users must check the transmitter and RC for missing cells.
Secondly, there are chances that even though the cells may be connected, they may be inserted incorrectly. It is essential to make sure that the batteries are correctly placed in their place, in the correct slots and facing the right direction. Thirdly, users should take care to change their batteries regularly.
Old batteries lose charge over time and result in poor performance of the RC, but people do not understand the need to change old batteries unless they stop working completely. In case of using a battery pack, they must ensure that it is properly charged.
Lastly, exposure to air and moisture as well as leaving the batteries in the slots unused can cause corrosion. Corrosion deteriorates the performance of the battery which in turn affects the device. To prevent this from happening, users should clean the battery slots regularly.
Wiring Should be Reconnected
Some problems can emerge due to broken or loose wiring. A loose wire from the motor can make the car stop moving in spite of being able to move the steering, and a loose wire to the steering signal can result in a lack of steering.
Sometimes the RC may refuse to work although the batteries are in excellent condition; this indicates loose wiring or poor connection between the vehicle and battery. Resoldering and rewiring are practical solutions to such problems.
There are many different varieties of RC cars that are powered by different materials. One such variety is the nitro RC which has a reputation for being a fussy intricate piece of machinery. It runs on nitro fuel. Thus, it is imperative that in case the equipment stops working, the users should first check the fuel tank as well as fuel line.
An empty or half empty fuel tank can affect the performance of the device. Moreover, a kink in the fuel line can also result in the RC car refusing to start. A complete fuel check may be needed if simple inspection does not reveal the cause of the problem. Such an examination is rather simple, but it takes a longer time.
Testing the Servos
Like all other parts of the mechanism, the servo also requires the necessary testing to rule out any problems that problems that may stem out of that part of the equipment. The response of the RC to a selective number of commands while being non-responsive to other commands could be an indication of a problem in the servo.
One can attempt to rectify such a problem by matching the frequency of the transmitter with a different receiver that is in working condition and re-plugging the servos to it after unplugging them from the nonresponsive receiver of the RC.
Despite this change of the receivers, if it still does not work, then there may be a problem with the servo. It is better to seek assistance from a hobby center or RC club for testing if the user is unsure of their approach towards the internal parts.
Using the Correct Frequency and Transmitter
Users of the RC cars must also be open to the possibility that problems with the devices may occur due to loopholes that may be as simple as having a transmitter with the wrong frequency. Those who own some RC toy cars can get confused about the correct transmitter for each car as they can easily mix them up.
The surest way to check that the right controller is being used for the exact car is by checking the writing on both the equipment. The frequencies that are usually engraved on them should be the same for both. Moreover, individuals must take special care to check such details while purchasing second-hand RC cars which could be sold with incorrect transmitters.
Gears May Require Resetting
A grinding noise accompanied by the RC being immovable is a sign of problems with the gears. Usually, tightening of the pinion gear to realign it with the spur gear is sufficient to make the RC car work. However, if the gears have been stripped away, they may need to be replaced. Also, slipped gears make it impossible for the RC vehicles to move.
Repairing broken steering arms and inspecting antennas
The user must ensure that the telescoping antenna on the vehicle must be fully extended to allow full functioning. It helps to increase the range of receiving commands. Users should also check whether their RC is wobbling while moving as it may be indicative of broken steering. The steering could be replaced with a piece of stiff wire.
